Muscle Booster Workout Planner

What Muscle Booster is and who it suits

Muscle Booster Workout Planner is a fitness app for men and women who want to build muscle, lose weight or stay fit, whether they train at home or in a gym. The developer presents it as an alternative to a personal trainer, with plans covering calisthenics, weight loss and gym-based muscle programs.

The developer describes the plans as general fitness guidance and says they are not a substitute for medical advice. Health conditions and physical limits are part of the plan setup, covered below.

Building a plan from goals, body details and equipment

You choose a goal (weight loss, muscle gain, strength, flexibility or injury recovery) and target areas such as arms, core, abs, chest, legs, shoulders or full body. You then enter age, gender, height, weight and fitness level, pick home or gym, and select the equipment you have or a calisthenics-only route.

You also note injuries or cardiovascular concerns, set the days and times you can train, and turn on personal reminders. An AI fitness test evaluates your current level, and the plan is built from these answers using the app's algorithm for sets, rep ranges and rest intervals. The full plan builder needs a subscription, and the free version offers limited functionality.

Workout library and the Workout Player

The library holds more than 1,000 workouts for building muscle, losing weight and recovering. Categories include Morning Routines, Calisthenics, Fat Burning, Chair Workouts, Dumbbells, 6-Pack Training and Injury Recovery, and challenges are matched to your profile.

In the Workout Player, each session has audio tips, guided instructions and muscle group targeting, along with a built-in workout and rest timer that also works with Apple Watch. Fitness guides and VIP customer support can be bought in the app as optional one-time or recurring purchases.

Tracking muscle recovery and progress

After each workout, the tracker shows which muscle groups to train next and which need recovery. Every plan lists an estimated workout time and calorie burn. Mini Milestones mark progress as you keep up consistent training.
